For Flyers forward Danny Briere, the news keeps getting worse.

The Flyers announced Monday that Briere would be sidelined indefinitely because of a concussion. He was injured during Saturday's practice in Voorhees, crashing into the boards during a drill.

Defenseman Nick Grossmann was injured during Friday's practice and is day to day with an unspecified upper-body injury.

"That's part of hockey and that happens," said defenseman Kimmo Timonen before the team released the extent of Briere's injury. "That tells you how hard we practiced actually that week....You never want to lose two players because of practice, but it's part of the game and I've seen that happen. Hopefully, these guys get back soon."
